Fire-Fighting Foam Truck Isuzu (also called foam fire fighting vehicle , Fire engine , Foam Fire service truck , Fire and rescue truck , Foam fire tank truck , Fire extinguishing foam tanker ) is a vehicle designed primarily for fire fighting operation to extinguish fire efficiently to prevent fire spread , reducing the loss caused by fire maximumly .

As a special fire-fighting equipment, the Fire-Fighting Foam Truck Isuzu has precise and scenario-based fire-fighting capabilities:

‌Applicable scenarios‌

‌Mobile fuel disasters‌: For dynamic disasters such as fire waterfalls caused by crude oil leakage and three-dimensional fires in oil tank areas, the foam curtain wall can build a three-dimensional isolation barrier to quickly block the combustion chain reaction‌。

‌High-risk liquid fires‌: In petrochemical terminals, aviation fuel storage and transportation bases and other scenarios, the intelligent injection system forms a molecular-level foam covering layer to effectively extinguish non-water-soluble liquid fires such as gasoline and diesel‌。

‌Special scenario protection‌: In the event of a fuel leak on an airport runway, a safe operating area can be quickly established ; Multiple complex disasters of suppressing liquid fire and solid fire at the same time in chemical plant room。

Inapplicable scenarios

Water-sensitive disasters: When water-soluble flammable liquids such as alcohol and acetone burn, the foam covering layer will be dissolved, resulting in protection failure

Energy interactive fire: Fires of live equipment have the risk of conductivity, and new fires such as thermal runaway of lithium batteries need to be used with dry powder fire extinguishing agents

The latest technology iteration enables foam fire trucks to have "environmental self-adaptation" characteristics. Through the compressed air foam system (CAFS), the foam viscosity and permeability can be intelligently adjusted. When dealing with crude oil storage tank fires, it can penetrate the oil layer to form a protective film to prevent re-ignition .

The fire extinguishing principle of the foam fire truck is based on multiple physical flame retardant mechanisms, and its core work flow can be divided into three stages:

1. Fire extinguishing principle

‌Oxygen isolation suffocation‌

High-multiple foam is sprayed through the compressed air foam system (CAFS) to form a continuous covering layer to isolate the burning material from oxygen and destroy the oxidant conditions in the three elements of combustion‌.

‌Thermal blocking‌

The foam layer can reflect more than 80% of the flame radiation heat, and the precipitated water absorbs heat through evaporation to reduce the surface temperature of the burning material, achieving double cooling‌.

‌Liquid film protection‌

Fluoroprotein foam can form a water film on the surface of oil, prevent the volatilization of fuel vapor, and suppress the risk of re-ignition, which is particularly suitable for oil tank fire fighting‌.

FC-336 is a kind of amphoteric type fluorosurfactant which is used as additives in fire suppressant products to reduce surface tension and improve the effectiveness in suppressing Class B fires. FC-336 is based on C6 technology and PFOS-free, so it is a environmental friendly product.

2. System working principle

‌Mixed liquid supply system‌

The fire pump mixes the water in the water tank with the foam storage tank concentrate at a ratio of 3%-6%, and achieves precise proportioning through the Venturi tube‌.

‌Intelligent spray control‌

Equipped with adjustable foam cannon, it can switch between low-multiple foam (suitable for flowing fire) or high-multiple foam (suitable for three-dimensional space filling) according to the needs of the fire scene. ‌

3. Typical operation process ‌Connect the pressure water source (≥0.6MPa) to start the fire pump‌

Complete the water-foam stock solution mixing through the proportioning mixer‌

Use the fire cannon/foam tube gun to implement directional spray‌

4. Application restrictions ‌Special anti-soluble foam is required to fight water-soluble liquids (such as alcohol) ‌

Fire of live equipment needs to be used with dry powder fire extinguishing agent‌

The latest technology upgrade enables the foam fire truck to have the "environmental perception-formula adaptation" function, which can analyze the material composition of the fire scene in real time through the on-board sensor, and automatically switch the type of fire extinguishing agent such as ordinary protein foam/fluoroprotein foam/water film-forming foam‌.

Fire-Fighting Foam Truck Isuzu have significant application value in forest fire fighting, and their applicability is reflected in the following technical characteristics:

1. Core application capabilities

‌ Rapid suppression of the fire line ‌

By spraying low-multiple foam (expansion ratio 20:1) through high-pressure foam cannons, a barrier belt with a width of 10-15 meters can be formed along the fire line spread path to block the contact between the flame and the unburned vegetation. This method is more than 40% more efficient than traditional water mist firefighting.

‌Three-dimensional fire scene coverage ‌

For high-intensity fires such as crown fires, high-multiple foam (expansion ratio 500:1) can cover the burning crown to form an insulation layer, while penetrating into the humus layer to suppress the re-ignition of underground fires.

2. Equipment adaptability ‌ Anti-corrosion tank design ‌

The use of stainless steel or epoxy resin coated tanks is resistant to corrosion by humus acidic substances, ensuring continuous combat capability in complex forest environments. ‌

‌Off-road mobility‌

Equipped with an all-terrain chassis and a high-power water pump, it can achieve 2.5km/h mobile spraying operations in mountains with a slope of ≤30°‌.

3. Collaborative combat mode

‌Cooperation with aviation forces‌

Ground foam spraying and aerial firefighting form a three-dimensional prevention and control system, which is particularly suitable for large-scale fires with a fire area of ​​more than 50 hectares‌.

‌Water supply innovation‌

Through the on-board water circulation system, water sources in forest streams and swamps can be extracted for foam mixing, breaking through the water source dependence restrictions of traditional fire trucks‌.

Actual application data shows that in the 2024 Daxinganling fire, the cluster operation of foam fire trucks shortened the fire control time to 1/3 of the traditional method‌. Its foam covering layer can last for 2-4 hours, creating a safe window period for subsequent manual fire cleaning‌.
